Discussion

In a fibre-reinforced composite, the fibres principally provide

  • A.Stiffness and strength along their own direction
  • B.Resistance to environmental attack
  • C.The shape of the component
  • D.Toughness in the through-thickness direction

Answer: A

The fibres carry the load along their length while the matrix binds them, transfers load between them and protects them. The consequence is a material far stronger along the fibres than across them, which is the defining feature of composite design.
